Microsoft 认知语音服务 - Android

Question

我正在 Android 应用程序上使用 Microsoft 认知服务 - 语音识别。当代码在我的主 activity 中时一切正常，但是当我想将与语音识别对应的部分移动到新的 class 时，它会抛出错误。

以下是代码示例：

主要activity

int m_waitSeconds = 0;
MicrophoneRecognitionClient micClient = null;
FinalResponseStatus isReceivedResponse = FinalResponseStatus.NotReceived;
Boolean speechIntent = false;
SpeechRecognitionMode speechMode = SpeechRecognitionMode.ShortPhrase;

}

你可以清楚地看到它基本上是相同的代码但是在我调用 this.micClient.startMicAndRecognition() 之后它在 onError 函数中给了我这个错误； :

Error code: LoginFailed -1910505470

Answer 1

我解决了这个问题。我在这行代码中得到了一个错误的主键：

public String getPrimaryKey() {
    return Integer.toString(R.string.primaryKey);
}

这是因为主键太长，无法被处理器读取为整数，然后转换为字符串。我必须通过 getString(R.string.primaryKey) 从主 activity 获取主键，然后将其作为参数传递到 SpeechRecognition class.
